Zimmer Persona Trabecular Knee Implant Recall

The Trabecular Metal Tibial Baseplate of the Zimmer Persona Knee was Recalled on January 21, 2015. These knee implants had a high failure rate as a result of loosening of the tibial plate in the implant. These implants had been on the market since November 7, 2012. The implants that are failing are the uncemented implants. This knee implant also had a version that was used with cement and that version seems to be performing well.

They symptoms of a failing implant are radiolucent lines on x-rays and pain. The radiolucent lines on x-ray indicates that the bone in the tibia has not grown into the tibial base of the implant. This implant is designed to be hammered onto the tibia and then the tibia is supposed to grow into the porous surface of the bottom of the tibial plate. Apparently there is a design defect in the porous coating or the shape of the base plate that prevents the bone from growing into the plate and it becomes loose. This type of loosening is called aseptic loosening. This means that it becomes loose in the absence of infection. Infections can also cause knee implants to become loose and fail.

Zimmer sold 11,658 of these knee implants worldwide. In the U.S. they were sold in AK, AL, AZ, CA, CO, FL, IL, IN, KS, MA, MI, MN, MO, NC, NJ, NY, OH, OK, PA, TN, TX, UT, VA, WA, and WI. The recalled product numbers are: 42-5300-064-01, Size C, Left -02 Right
